Ok, I have been shooting the monolithic model with the two piece sight set.
The "pet" load thus far is 4.3gr W231, 147gr truncated lead, federal cases and win primers with an OAL of 1.155. Velocity at my elevation is averaging at 1145 fps (980ft above sea leavel at 78 degrees).
I also shot some of the RWS that Walmat has (124gr) and it liked that at 25yards. I will be doing some 50yard testing soon as the snow is now gone from the range..
